Tuberculosis of the liver: symptoms, diagnosis and why it is mistaken for cancer | CION Cancer Clinics
Liver TB usually shows itself as an evening fever, weight loss, a poor appetite and a dull ache under the right ribs. It is treatable with a full course of TB medicines. On a scan it can look very like a tumour, so in India TB and liver cancer are sometimes mistaken for each other. This page explains the symptoms, how a biopsy settles it, and when not to wait. At CION Cancer Clinics, our team goes through your scan, blood test and biopsy reports with you and plans the next step.

The short answer
What is tuberculosis of the liver?
Tuberculosis of the liver, or hepatic TB, is TB infection that has reached the liver. It usually causes a slow fever, weight loss, a poor appetite and a dull ache under the right ribs, and it is treatable with a full course of TB medicines.
Why it appears on a cancer website
Liver TB can form lumps that look very like a tumour on an ultrasound or CT scan. It can also look like cancer that has spread to the liver from somewhere else. In India, where TB is common, this mix-up happens in both directions. Some people are told they may have cancer and turn out to have TB. Others are treated for TB for months before a cancer is found. Either way, the delay is what does the harm.
How it reaches the liver
TB germs usually start in the lungs or the gut. They can travel in the blood to the liver, or spread from nearby lymph glands. Many people with liver TB have no cough and a normal chest X-ray, which is one reason it is missed. Liver TB in its own right is not a cancer and does not turn into one.
This page explains liver TB. It cannot tell you whether the spot on your scan is TB or something else.How it shows itself
What are the symptoms of liver TB?
Most of these signs are shared with many other illnesses, including ordinary infections and liver cancer. None of them proves TB on its own.
The slow, general signs
An evening fever that keeps coming back, sweating at night, weight loss without trying, and tiredness that does not lift. These build up over weeks rather than days.
Signs from the liver
A dull ache or heaviness under the right ribs. An enlarged liver the doctor can feel. Sometimes yellow eyes, dark urine or itching, when a lump presses on a bile duct.
Less often
- Fluid in the abdomen
- Swollen glands in the neck or abdomen
- A cough, if the lungs are also involved
The forms seen on a scan
Liver TB can appear as many tiny specks spread through the liver, or as one or more larger lumps. The larger lumps are the ones most often mistaken for a tumour or for an amoebic liver abscess.
Who is more likely to have it
People who have had TB before, live with someone who has it, have diabetes, HIV or kidney disease, or take medicines that lower the body's defences. Anyone can get it, and having it is not a sign of poor hygiene.

When this cannot wait
Go to hospital today if there is high fever with shivering, sudden yellow eyes with fever, severe pain in the abdomen, vomiting blood, black stools, or new confusion or drowsiness. Go today too if someone on TB medicines develops yellow eyes, vomiting or a swollen, painful abdomen, because the medicines themselves can damage the liver. Do not stop or restart TB tablets on your own. See a doctor this week for an evening fever with weight loss and a liver spot on a scan.
How it is confirmed
How do doctors know it is TB and not cancer?
-
A careful history
Past TB, TB at home, fevers, weight loss, diabetes, hepatitis B or C and alcohol all shift the picture. Mention every medicine you take, including herbal ones.
-
Blood tests and a chest scan
Liver function tests, a blood count, markers of infection and sometimes AFP. A chest X-ray or CT looks for TB in the lungs. A normal chest scan does not rule out liver TB.
-
A contrast CT or MRI of the liver
This shows the size, number and pattern of the lumps. It can point towards TB or towards cancer, but it often cannot settle the question alone. CION arranges these scans through diagnostic partners.
-
A biopsy, which usually decides it
A thin needle takes a small sample. The pathologist looks for the typical TB pattern, and the lab tests the sample for TB germs and their DNA. The same sample can show cancer if it is there. Read what happens on the day of a liver biopsy.
-
A check that treatment is working
Once TB treatment starts, the doctor watches the fever, weight and a follow-up scan. If the lumps do not respond as expected, the diagnosis is reviewed.

Commonly believed
What do families often believe about liver TB?
"There is no cough, so it cannot be TB."
TB outside the lungs often comes with no cough at all. Liver TB can be the only place the infection shows, and the chest X-ray can be clear.
"TB tablets were started, so the cancer question is closed."
Doctors sometimes start TB treatment on a strong suspicion, before proof. That is reasonable, but only with a plan to check the response. If the lumps do not shrink, ask whether a biopsy or a second opinion is needed. Read why liver TB and liver cancer look alike.
"The fever went away, so the tablets can stop."
Feeling better comes long before the infection is cleared. Stopping early lets TB return and can make it harder to treat. The full course matters.
"TB in the family is something to hide."
TB is an infection, not a mark against anyone. Telling the doctor about TB at home is one of the most useful clues they can get, and it helps protect the rest of the family.
Being straight with you
What this page cannot tell you
It cannot tell you whether the spot on your scan is TB, an abscess, a harmless lump or a cancer. That answer comes from the doctor who has seen your images, your blood results and, often, a biopsy. It also cannot tell you which TB medicines are right for you.
Who looks after liver TB
TB itself is treated by a physician, chest specialist or hepatologist through the TB services. TB medicines can strain the liver, so blood tests are checked during treatment. Read more about TB medicines and liver damage.
Who this page does not apply to
If a biopsy has already shown cancer, the TB question is answered. If you have both liver cancer and active TB, the two are planned together; see liver cancer with active TB. CION's oncologists can review a scan and biopsy as a second opinion when TB and cancer cannot be told apart.
If you are unsure who should see your report, call the helpline and someone will point you to the right doctor.Questions we are asked
Common questions about liver TB
Is liver TB curable?
Yes. Liver TB is curable with a full course of TB medicines taken without gaps. The course lasts several months and is supervised through the TB services. Taking every dose matters more than anything else.
Can liver TB turn into cancer?
No. TB is an infection and does not change into cancer. The worry is different: the two can look alike on a scan, so one can be mistaken for the other for a while. A biopsy usually settles which one it is.
Is liver TB infectious to my family?
TB that is only in the liver is usually not passed on by breathing. If the lungs are also involved, it can be. Your doctor will check, and family members with a cough, fever or weight loss should be tested without blame.
Why do I need a biopsy if the doctor suspects TB?
Because TB treatment is long, and starting it for something that is not TB delays the right treatment. A biopsy sample can confirm TB, show which medicines will work, and rule out cancer at the same time.
What does a TB pattern on a biopsy report mean?
Reports often mention granulomas, small clusters of defence cells, and caseation, a cheesy dead area typical of TB. These strongly suggest TB, but a few other conditions cause granulomas too. Your doctor reads them with the lab tests for TB germs.
Can TB medicines harm the liver?
Yes, some can. That is why liver blood tests are done before and during treatment. Report yellow eyes, vomiting or pain in the abdomen straight away. Never stop the tablets yourself; the doctor will decide what to change.
What if the liver spots do not shrink on TB treatment?
Tell your doctor and ask whether the diagnosis should be checked again. Sometimes the TB is resistant to the usual medicines. Sometimes it was never TB. A repeat biopsy or a second opinion from an oncologist can settle it.
Where can I get a second opinion on my scan?
Bring the scan images, the reports and any biopsy slides to a medical oncologist or hepatologist. CION's tumour board can review them and arrange further tests through partners if needed. One helpline serves every CION centre.
